Cold Formed Heads
Cold Formed Heads
(OP)
At what (ballpark) temperature are "Cold"- formed heads spun/formed at??
Can they be heat treated after being cold formed and THEN welded to the vessel Shell.
I'm trying to avoid heat treating the entire Pressure Vessel and I'm stuck using these cold formed heads.

Below 900 deg F for steel/low alloy steel
Yes. They can be subjected to a re-normalization heat treatment or subcritical thermal treatment per UCS-56.
